It’s quite big (6711140776), but plays well with ffplay or vlc. I will try to encode it so that it becomes smaller, but is there anything else I could do?
I made a yuyv422 transcode of some other video I had, and it opened in Shotcut fine.
I doubt file size is an issue. Shotcut has handled much larger files than 7 GB.
So that leaves me wondering about the frame rate (is it variable or constant?) and the integrity of the MKV wrapper (did the camera lose power while recording?). Both could be tested by rewrapping the video in a new container like this:
Note this is a video-only rewrap. If the new file works, I can walk you through a rewrap that includes audio stretched as necessary for the conversion to constant frame rate.
frame= 890 fps= 11 q=-0.0 Lsize= 3604542kB time=00:02:39.03 bitrate=185672.4kbits/s speed=2.02x
video:3604500kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.001177%
ShotCut crashes the same way with this new file.
I also rewrapped another file that makes Shotcut crash, and the rewrapped file makes ShotCut crash too.
The command was:
Hmm, I’m not sure then. It works for me, which isn’t a satisfying answer to you of course. What about transcoding the video to a different format altogether? It could be something lossless like Huffyuv or Ut Video if you wanted to retain full quality.
